Moon, S; Yang, B and Choi, E (2018) Safety guideline for safe concrete placement utilizing the information on the structural behavior of formwork. Journal of Construction Engineering and Management, 144(12): 04018108, ISSN 0733-9364
Abstract
Temporary structures are designed from complex structural analyses. Concrete formwork is a representative temporary structure, and frequently fails during construction due to unexpected external factors. Therefore, safety managers should constantly monitor structural behavior to determine whether the formwork is performing safely. Information on structural behavior provides knowledge on the characteristics of actual temporary structures and can help ensure safe concrete placement. The objective of this study is to present a guideline for safe concrete placement based on an understanding of the structural behavior of concrete formwork. Using ubiquitous sensor network devices, an indoor test bed was built to test the structural behavior of concrete formwork. Eight scenarios were investigated, representing typical safety conditions that occur for concrete formwork. Finite-element analysis was conducted for these scenarios to provide a guideline for safe concrete placement. Laboratory loading tests conducted on the test bed validated that the safety guideline provided a suitable procedure to cope with abnormal behaviors on concrete formwork and can be applied to ensure safe concrete placement.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
